A day after authorities identified Bailey's body and two others found on an Ottawa farm, they learned that law enforcement authorities also believe that Bailey's 18-month-old daughter Lana was also killed.

"We are numb," said Lana's great aunt, Linda Journey, shortly after hearing the news.

"(It's) really senseless," said Kaylie Bailey's grandfather Andy Pettijohn. "The other killings are not understandable, but that one, really, I can't understand. You think, 'Why would you kill this little girl? She can't identify him. She can't talk to anybody.'"

He showed KMBC 9's Jana Corrie Lana's favorite toy, a bunny that recorded her laughter.

"That was one of her favorites," he said "She giggled every time she heard herself giggling."

Kaylie and Lana lived in her grandfather's Olathe home for the past six months after she began the process of divorcing the baby's father, who is currently jailed in Missouri. The family said the divorce was set to be finalized next week.
